On Rob & Chyna, Rob and his pregnant fiance Blac Chyna seem to be working hard to get on better, closer terms with the Kardashians. Unfortunately, according to the father-to-be, relations between the famed E! reality TV show family and Chyna may not be so cordial offset.

On Monday night, Rob (or someone who has convincingly hacked him) blasted his sisters on Twitter, revealing that in a shockingly cold move, they were apparently not planning to invite the future mother of his child to the baby shower they were planning to throw.

"Didn't invite the Mother of my child to a baby shower you all were trying to throw for me?" Rob wrote on Twitter.

"You all must have lost your damn minds," he added.

In another set of tweets, Rob seemingly posted his sister Kylie Jenner's personal phone number—a number which has since been disconnected—for all the world to see.

As countless fans have noted on Twitter, the number seems to be real: At one point, the digits were reportedly connected to Kylie's Instagram account, though since it was exposed many users have taken to using the number on their own accounts.

So far, none of the Kardashians have responded to the mounting drama on Twitter or social media. But the question remains: Did they really not invite Blac Chyna to her own baby shower?
